Just for argument sake, Glock 9mm pistols are rated for +P+ ammunition and handle it quite well. Winchester RA9TA 127 grain +P+ ammunition departs the muzzle of a G17 in excess of 1,300 fps, which is quite close to real world .357 Sig velocities.
S&W specifically advises against the use of +P+ ammunition in it's 9mm pistols.
Some major departments have standardized on the G17 loaded with RA9TA +P+. I'm certain that Glock would take North Carolina's conglomeration of pistols in trade and make them an incredible deal on the G17. There is some value to a standard issue sidearm. The G26 (or G19) handles the same +P+round extremely well for plainclothes, off duty and BUG use. Those weapons will, in a pinch, use G17 magazines.
No one is going to "stop" a car with a handgun anyway. Maybe a 7.62 rifle or an RPG, but not a handgun. Handguns are defensive anti-personnel weapons. A 9mm+P+ fulfills that role nicely.
